Let’s visualize all terrorist attacks on the map

mapIND %>% addCircles (data=TIN, lat= ~latitude, lng = ~longitude, 
              popup=paste(
                "<strong>Year: </strong>", TIN$iyear,
                "<br><strong>City: </strong>", TIN$city, 
                "<br><strong>Country: </strong>", TIN$country_txt, 
                "<br><strong>Attack type: </strong>", TIN$attacktype1_txt, 
                "<br><strong>Target: </strong>", TIN$targtype1_txt, 
                " | ", TIN$targsubtype1_txt, 
                " | ", TIN$target1, 
                "<br><strong>Weapon: </strong>", TIN$weaptype1_txt,

              weight = 0.9, color="#8B1A1A", stroke = TRUE, fillOpacity = 0.6)

1.0 let’s have a look at terrorist attacks globally by attack type

ggplot(GT, aes(x = iyear))+ labs(title =" Terrorist attacks globally between 1970-2015 by attack type", x = "Years", y = "Number of Attacks", size = 15) + 
  geom_bar(colour = "grey19", fill = "tomato3") + facet_wrap(~attacktype1_txt,scales = "free", ncol = 3) + 
  theme(axis.text.x = element_text(hjust = 1, size = 12)) + theme(strip.text = element_text(size = 16, face = "bold"))

2.1 Terrorist attacks on Turkey between 1970-2015 by ATTACK type

ggplot(TIN,aes(x = iyear))+ labs(title =" Terrorist attacks on Turkey between 1970-2015 by attack type", x = "Years", y = "Number of Attacks") + 
  geom_bar(colour = "grey19", fill = "tomato3") + facet_wrap(~attacktype1_txt) + theme(axis.text.x = element_text(hjust = 1, size = 12))+
  theme(strip.text = element_text(size = 16, face = "bold"))

2.2 Yearwise terrorist attacks by ATTACK type in Turkey

ggplot(data=TIN, aes(x=iyear,fill=attacktype1_txt)) + geom_bar() + ggtitle("Yearly terrorist attacks by attack type in Turkey")+         
    labs(x = "Years", y = "Number of Attacks")

3.1 By TARGET type

TINclean = TIN[which(TIN$targsubtype2_txt !='.'), ] 

ggplot(TINclean, aes(x = iyear))+ labs(title =" Terrorist attacks on Turkey between 1970-2015 by TARGET type", x = "Years", y = "Number of Attacks") + 
  geom_bar(colour = "grey19", fill = "tomato3") + facet_wrap(~targtype2_txt, ncol = 4) + theme(axis.text.x = element_text(hjust = 1, size = 12))+
  theme(strip.text = element_text(size = 16, face = "bold"))

3.2 Yearwise terrorist attacks globally by TARGET type

ggplot(GT, aes(x=iyear,fill=targtype1_txt)) + geom_bar() + ggtitle("Yearly terrorist attacks globally by TARGET type")+         
    labs(x = "Years", y = "Number of Attacks")

4.1 By WEAPON type

ggplot(TIN, aes(x = iyear))+ labs(title =" Terrorist attacks on Turkey between 1970-2015 by WEAPON type", x = "Years", y = "Number of Attacks") + 
  geom_bar(colour = "grey19", fill = "tomato3") + 
  facet_wrap(~weaptype1_txt, ncol = 2) + theme(axis.text.x = element_text(hjust = 1, size = 12))+ theme(strip.text = element_text(size = 15, face = "bold"))

4.2 Yearwise terrorist attacks by WEAPON type

ggplot(data=TIN, aes(x=iyear,fill=weaptype1_txt)) + 
    geom_bar() + ggtitle("Yearly terrorist attacks in Turkey by WEAPON type")+ 
    labs(x = "Years", y = "Number of Attacks")

5.1 By Terrorist Groups

ggplot(TIN, aes(x = iyear))+ labs(title =" Terrorist attacks on Turkey between 1970-2015 by GROUP", x = "Years", y = "Number of Attacks") + 
  geom_bar(colour = "grey19", fill = "skyblue") + 
  facet_wrap(~gname, ncol = 5, scales = "free_y") + theme(axis.text.x = element_text(hjust = 1))+
  theme(strip.text = element_text(size = 11, face = "bold"))

(Y axis scale is set to free on Y axis for the plot 5.1)
